The utility model provides a circular cavity hydrostatic thrust bearing's tilting -type lubricating pad. High -speed heavy load is the in -process of the high -speed operation of hydrostatic thrust bearing down, because oil stream inertia causes and gets rid of oil and increase, cuts the increase of generating heat, and the lubricating oil viscosity descends and leads to clearance oil film attenuation, and oil film temperature nonuniform distribution produces the too high oil film elastic deformation that leads to of local hot the local temperature in addition, and the supporting friction is vice warp inhomogeneously, and lubricated condition is abominable, and the in this case can lead to hydrostatic thrust bearing's friction inefficacy. In order to capture this difficult problem, the utility model provides a design into the tilting -type with the static pressure lubricating pad, utilize dynamic pressure compensation static pressure bearing capacity not enough, reach the effect that sound pressfitting reason is matchd. The utility model discloses well lubricating pad main part is big quadrant, and its inside is a circular oil pocket, and processing has the inlet port in this circular oil pocket. The lower facing (operation) of lubricating pad main part has cylindrical boss, and cylindrical boss has certain height. The utility model is used for the work of fluid pressure thrust bearing high accuracy.
